the camera writes at about 7-8 MB per sec, which is about 32X... So any faster card will not help in picturetaking, only when reading from a card you may save a second or two.... Look for a good brand, like Transcend at NEWEGG.COM or sandisk... The Sandisk ULTRAII PLUS, with a vuilt in USB connector in the card is on sale at RadioShack for $59.0
